Name all ioctl references and make them match the ioctls that are documented. That will improve the cross-reference index, as it will have all ioctls and syscalls there. While here, improve the documentation to make them to look more like the rest of the document. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

Description
|
|
===========
|
|
|
|
Retrieves the code length in bits (only for ``LIRC-MODE-LIRCCODE``).
|
|
Reads on the device must be done in blocks matching the bit count.
|
|
The bit could should be rounded up so that it matches full bytes.
|
|
|
|
|
|
Return Value
|
|
============
|
|
|
|
On success 0 is returned, on error -1 and the ``errno`` variable is set
|
|
appropriately. The generic error codes are described at the
|
|
:ref:`Generic Error Codes <gen-errors>` chapter.
